Make sure the kernel module has been loaded successfully. It is common on OSX to see an error like this: If you still have trouble after this, feel free to visit me in my office or shoot me an email at Kernel Driver Not Installed error Turn the Graphics Controller to VBoxVGA (Settings > Display).Make sure 2d/3d acceleration is turned off (Settings > Display).Additional tips for improving performance on OSX: View the image below:Īfter this is done, open up a new instance of VirtualBox and you should find the performance improved. I find that 1440x900 is fine for visibility and performance, and going above 2560x1440 or more strains Vbox. Preferably a lower resolution, as there is a tradeoff between pixels and performance occurring. Click it, and select a resolution WITHOUT a lightning bolt next to it. After installing properly, you should see a little screen icon in the top right of your screen on your toolbar.(If you use the DMG, you will have to open finder, look on the left for RDM, and click the PKG file in there). Once at that directory, click either the DMG or the PKG file for the latest version, and install normally. Simply navigate to that link, scroll to the bottom, find where it says "installable binary package?" and follow that link. MAKE SURE TO INSTALL THIS IN YOUR HOST MACHINE, NOT INSIDE VBOX. The second solution is to simply rescale the host resolution to a lower one, so VirtualBox can function. You should notice immediate improvement in usability. A quick and easy workaround is to plug your computer into a secondary non-HiDPI monitor and move the virtual machine guest window to that screen. This results in very laggy window movement, typing, and overall updating of the screen to any changes. 5 Screen Flickering on OSX screens (or other)Ī common issue on newer Macbook pros is that VirtualBox scales very poorly to the host display when it is a HiDPI resolution.
